If there was a semantic wishlist I could put something on, I know what I'd
put on it: Having you guys locked in an office together, so you could work,
undisturbed, on a tool which combines the power of all your tools into one.
  :)

And I'm only half kidding with that. One of the things I'm struggling with
in offering Semantic markup services is the amount of time it takes not
only to design data models and then marking it all up but also the time it
takes to validate it all. I estimate just the markup validation process
takes about 20%-40% of the time on any project where I mark up beyond just
an Article or Product template. Simply because the different tools
available (and mentioned) somehow always end up with returning a slightly
different outcome. Which leads to having to compare all those different
outcomes with each other and trying to dedact if I got it right. A very
time consuming and therefore costly process.

Besides the 'gap' in proper documentation I think this is also one of the
things that's holding back the implementation of more extensive markup on
websites. The costs involved are keeping it exclusive for those select few
who can pick up the bill. Having better tools/software for this would
seriously help cut back costs and make it more accessible. For both the
organizations offering these types of services as well as their possible
clients - who are the ones who have to pay for it after all.

That's what lead to my original question. I'm looking for ways to cut the
costs of semantic markup so more website owners can afford going beyond the
basics. Mind you, I don't want to give the impression I think the mentioned
tools are anything less than marvelous but from a commercial standpoint, I
need more than is being offered right now.
